<p>Preamble</p>

<p>
  This license establishes the terms under which a given free software Package

  software.

<p>
  You are always permitted to make arrangements wholly outside of this license
  directly with the Copyright Holder of a given Package. If the terms of this
  license do not permit the full use that you propose to make of the Package,
  you should contact the Copyright Holder and seek a different licensing
  arrangement.

<h4>Permission for Use and Modification Without Distribution</h4>
<ol type="1">
  <li>
    You are permitted to use the Standard Version and create and use Modified
    Versions for any purpose without restriction, provided that you do not
    Distribute the Modified Version.
  </li>
</ol>
<h4>Permissions for Redistribution of the Standard Version</h4>
<ol type="1" start="2">
  <li>
    You may Distribute verbatim copies of the Source form of the Standard
    Version of this Package in any medium without restriction, either gratis or
    for a Distributor Fee, provided that you duplicate all of the original
    copyright notices and associated disclaimers. At your discretion, such
    verbatim copies may or may not include a Compiled form of the Package.
  </li>
  <li>
    You may apply any bug fixes, portability changes, and other modifications
    made available from the Copyright Holder. The resulting Package will still
    be considered the Standard Version, and as such will be subject to the
    Original License.
  </li>
</ol>
<h4>Distribution of Modified Versions of the Package as Source</h4>
<ol type="1" start="4">
  <li>
    You may Distribute your Modified Version as Source (either gratis or for a
    Distributor Fee, and with or without a Compiled form of the Modified
    Version) provided that you clearly document how it differs from the Standard
    Version, including, but not limited to, documenting any non-standard
    features, executables, or modules, and provided that you do at least ONE of
    the following:
  </li>
  <ol type="a">
    <li>
      make the Modified Version available to the Copyright Holder of the
      Standard Version, under the Original License, so that the Copyright Holder
      may include your modifications in the Standard Version.
    </li>

    <li>
      ensure that installation of your Modified Version does not prevent the
      user installing or running the Standard Version. In addition, the Modified
      Version must bear a name that is different from the name of the Standard
      Version.
    </li>

    <li>
      allow anyone who receives a copy of the Modified Version to make the
      Source form of the Modified Version available to others under
      <ol type="i">
        <li>the Original License or</li>

        <li>
          a license that permits the licensee to freely copy, modify and
          redistribute the Modified Version using the same licensing terms that
          apply to the copy that the licensee received, and requires that the
          Source form of the Modified Version, and of any works derived from it,
          be made freely available in that license fees are prohibited but
          Distributor Fees are allowed.
        </li>
      </ol>
    </li>
  </ol>
</ol>
<h4>
  Distribution of Compiled Forms of the Standard Version or Modified Versions
  without the Source
</h4>
<ol type="1" start="5">
  <li>
    You may Distribute Compiled forms of the Standard Version without the
    Source, provided that you include complete instructions on how to get the
    Source of the Standard Version. Such instructions must be valid at the time
    of your distribution. If these instructions, at any time while you are
    carrying out such distribution, become invalid, you must provide new
    instructions on demand or cease further distribution. If you provide valid
    instructions or cease distribution within thirty days after you become aware
    that the instructions are invalid, then you do not forfeit any of your
    rights under this license.
  </li>
  <li>
    You may Distribute a Modified Version in Compiled form without the Source,
    provided that you comply with Section 4 with respect to the Source of the
    Modified Version.
  </li>
</ol>
<h4>Aggregating or Linking the Package</h4>
<ol type="1" start="7">
  <li>
    You may aggregate the Package (either the Standard Version or Modified
    Version) with other packages and Distribute the resulting aggregation
    provided that you do not charge a licensing fee for the Package. Distributor
    Fees are permitted, and licensing fees for other components in the
    aggregation are permitted. The terms of this license apply to the use and
    Distribution of the Standard or Modified Versions as included in the
    aggregation.
  </li>
  <li>
    You are permitted to link Modified and Standard Versions with other works,
    to embed the Package in a larger work of your own, or to build stand-alone
    binary or bytecode versions of applications that include the Package, and
    Distribute the result without restriction, provided the result does not
    expose a direct interface to the Package.
  </li>
</ol>
<h4>Items That are Not Considered Part of a Modified Version</h4>
<ol type="1" start="9">
  <li>
    Works (including, but not limited to, modules and scripts) that merely
    extend or make use of the Package, do not, by themselves, cause the Package
    to be a Modified Version. In addition, such works are not considered parts
    of the Package itself, and are not subject to the terms of this license.
  </li>
</ol>
<h4>General Provisions</h4>
<ol type="1" start="10">
  <li>
    Any use, modification, and distribution of the Standard or Modified Versions
    is governed by this Artistic License. By using, modifying or distributing
    the Package, you accept this license. Do not use, modify, or distribute the
    Package, if you do not accept this license.
  </li>
  <li>
    If your Modified Version has been derived from a Modified Version made by
    someone other than you, you are nevertheless required to ensure that your
    Modified Version complies with the requirements of this license.

    Copyright Holder that are necessarily infringed by the Package. If you
    institute patent litigation (including a cross-claim or counterclaim)
    against any party alleging that the Package constitutes direct or
    contributory patent infringement, then this Artistic License to you shall
    terminate on the date that such litigation is filed.
